S!
Not being a programmer, just an average joe, but IMHO they should drop DirectX 9.0c and focus on DX 10/11 as ANY decent GPU these days can handle both. Backwards compatability is like an anchor slowing you down. Look at Frostbite engine used in BF3 for example, it will go 64-bit ONLY in a year. No more limitations of 32-bit like 3Gb RAM or whatever. That would be future proof, not dragging relics with you. Just some thoughts, propably not very educated but nevertheless
Thoughts?
